There are three storms to watch. The initial phase hits the Sierra Thursday with moderate, decent-quality powder. The second surge of moisture brings in warmer, windier, and deeper snow for the Sierra on Saturday. The PNW and BC will grab heavy snowfall, favoring the north. Central Idaho, the Wasatch, and the Tetons should nab 5-11 inches this weekend, initially warm, followed by cooling.

A strong storm will bring a welcome round of snow to the Tetons this weekend. We will see a little bit of an appetizer on Friday with light snow showers/flurries, then the main event will be from Saturday evening to Sunday evening with moderate to heavy snow expected. A light/moderate refill is possible on Tue (Dec 17), then we will likely head into a warmer/drier pattern thru Christmas.

A ridge of high-pressure remains over the Northern Rockies through Thursday. A weak storm clips the western border (Lookout Pass /Lolo Pass) on Thurs PM – Fri AM that could bring an inch or two. The next storm on Sat-Sun is trending weaker, but widespread light accumulations are likely on both days. Unsettled skies last into early next week, with daily chances of light accumulations possible.

The West will see some welcome snow late this week and into the weekend after a drier start to December. A weak storm will move through on Thursday followed by a stronger storm Friday-Sunday. The Sierra (including Tahoe), Cascades, BC, and Northern Rockies will be favored for the deepest snow totals. The East will see rain & some snow Wed-Thu & again early next week with a warmer airmass in place.

Thanks for reading this summer! For the rest of this week, a cold front moving across the Central Rockies will bring showers & t-storms to WY, CO, & NM Wed-Thu while the West Coast states will see a late-season heat wave. Next week, isolated to scattered showers & t-storms develop across the West with continued mild temps. Heading into mid-month, the PNW will trend wetter and cooler.
